Description

Filler for Cooling Tower {A Filler for Cooling Tower}

The present invention relates to a filler for a cooling tower, and more particularly, to a filler for cooling water in contact with the atmosphere in a cooling tower, which is a heat exchange device for cooling the cooling water used in a condenser of a refrigerator.

Cooling water heated in the hot parts of refrigeration units, air conditioning units and industrial heat exchangers is reused after cooling in the cooling tower.

1 is a cross-sectional view showing the structure of a conventional cooling tower.

In the upper part of the cooling tower, a fan 1 is arranged to form an air flow from the lower side to the upper side, and a lower portion of the fan 1 is provided with a supply conduit 2 through which the heated cooling water is supplied. Thus, several nozzles 3 for spraying cooling water are arranged.

Fillers 4 having a flow channel of cooling water are arranged below the water supply pipe 2 so that the cooling water injected from the nozzle 3 flows down through the surface of the filling material 4.

The bottom of the filler 4 is provided with a space in which the ventilating window 5 is formed on the outer circumferential surface. When the upper fan 1 is operated, the outside of the air is introduced through the ventilating window 5 and then the filler 4 is opened. The cooling water is cooled by contacting the cooling water while flowing upward.

The coolant is dropped from the filler material 4 and the lower drain box 6 is collected and then supplied to the refrigerating device or the air conditioner through the discharge conduit 7.

As described above, in the cooling tower, the cooling water heated in the filler 4 is sprayed and flowed downward by gravity to be in contact with the atmosphere from the outside to be cooled while performing heat exchange to return to the air conditioner for reuse.

The filler material 4 must be in contact with the atmosphere with a large contact area and a long contact time while the coolant sprayed from the nozzle 3 flows through the large surface area at the lowest possible flow rate.

As one of the methods for making the filler have a large contact area and a long contact time, Korean Patent No. 916545 (Document 1) and Korean Patent No. 929373 (Document 2) propose a filler for a cooling tower.

The fillers commonly proposed in Documents 1 and 2 are in the form of panels formed by alternating valleys and acids extending in the direction in which the cooling water flows, and the panel-shaped fillers overlap each other to contact the valleys of one filler and the other. A flow channel of coolant is formed which is surrounded by the acid of the filler.

This flow channel of coolant extends from the top to the bottom into which the sprayed coolant flows, forming grooves in each of the hills and valleys that intersect the flow direction of the coolant, thereby dispersing the flow of coolant and slowing the flow rate. This increases the area and time for the cooling water to contact the atmosphere.

In addition, as a method of laminating the fillers, the lamination protrusions and the lamination grooves are formed on the fillers so that the lamination protrusions and the lamination grooves are fitted to each other, and the lamination protrusions are deformed after the insertion, so that the coupling is performed.

However, the fillers of Documents 1 and 2 are not only difficult to stack because the stacking projections and the stacking grooves have to be matched with each other when they are laminated and bonded to each other. There is a problem that it takes considerable time and money to work.

In addition, the groove and the groove of the filler is formed grooves have the effect of increasing the area and time flow of the coolant, but the coolant sprayed from the top flows to the bottom through a flow channel surrounded by the bone and acid, even if the Even if the flow of the coolant flowing through the surface is delayed, the coolant falling through the space between the valley and the mountain may fall rapidly due to gravity.

On the other hand, Korean Patent No. 472312 (Document 3) proposes a filling material in which the flow channel of the coolant is zigzag-shaped, and according to this configuration, as the coolant flows through the zigzag channel, the fall time increases and The effect of increasing the contact area by hitting the surface is expected.

However, the filler of this document 3 also has to stack several fillers with each other to form a flow channel, but it does not provide any solution on how to fill the flow channels with each other and how to fill the fillers with each other.

Korean Patent No. 916545 (Document 1) Korean Patent No. 929373 (Document 2) Korean Patent No. 472312 (Document 3)

The present invention is to provide a cooling tower filler for the cooling water is introduced to form a flow channel of the cooling water flowing downward.

In particular, it is an object of the present invention to provide a filler of such a configuration that the cooling water can be sufficiently scattered in the flow channel and slow down the cooling water to increase the flow time.

In addition, the present invention provides a filler having a configuration in which a flow channel of the coolant is formed between the fillers against each other, but the fillers are easily bonded to each other without the need for a separate bonding or fixing operation The aim is to provide a filler with a configuration that can remain facing back.

The above-described problem of the present invention is achieved by the filling material for a cooling tower of the present invention in which a plurality of fillers are arranged to face each other and configured to form a flow channel of cooling water flowing from the upper side to the cooling water flowing in between the fillers. .

Filling material for a cooling tower of the present invention,

Each of the plurality of valleys and the peaks projecting opposite to each other in the thickness direction are disposed in the width direction, and are formed to extend inclined at a predetermined angle with respect to the vertical direction from the upper side to the lower side alternately in parallel.

An inclined surface is formed between the valleys and the peaks, the surfaces of the valleys and the surfaces of the inclined surfaces on both sides form a first flow channel of the coolant, and the rear surface of the peak and the rear surfaces of the inclined surfaces on both sides form a second flow channel of the coolant,

 The ridges and valleys are each formed in a plane, the surfaces of the hills are disposed in a common first plane, and the backsides of the valleys are disposed in a common second plane, with the first and second planes spaced apart from each other in parallel. ,

The first flow channel of the fillers is arranged such that the surfaces of the top of one of the fillers are in contact with the surfaces of the top of the other of the fillers or that the back of the valleys of one of the fillers is in contact with the back of the valleys of the other of the fillers. Or second flow channels are arranged opposite to each other.

According to this configuration, when either one of the filler and the other filler is stacked in contact with each other or the valleys are in contact with each other, the flow channels of the coolant disposed between the fillers do not flow out of the coolant by the other fillers. Although the passage is formed, the passage has a shape in which the first flow channels or the second flow channels cross each other.

For example, when the tops of the fillers are stacked to face each other, the first flow channels of the fillers face each other, but flow paths do not coincide with each other but cross each other.

Therefore, when the coolant flows between the fillers which are opposed to each other, the coolant does not flow along any one of the flow channels, but moves to another flow channel while colliding with the surface of the filler at the point where the flow channels intersect, thereby causing the coolant to aggregate. Without dispersion or scattering. In addition, the cooling water is not flowed quickly through any one flow channel is dispersed in the flow channel intersecting with each other, or the flow rate is lowered by colliding with the slope of the filler.

Therefore, in the laminate formed by laminating the filler of the present invention, the contact area of the cooling water with the atmosphere is increased, the residence time is increased, and the cooling is promoted.

On the other hand, as an additional feature of the present invention, a plurality of first protrusions protruding from the first plane are formed on the surface of the hill at regular intervals along the longitudinal direction of the hill, and a plurality of protrusions protruding from the second plane on the back of the valleys. Second projections are formed at regular intervals along the longitudinal direction of the valleys,

The first protrusion and the second protrusion are formed at positions where one filler is projected into the first flow channel and the second flow channel of the other filler when the filler is disposed in contact with the other filler, and the side surfaces of the first protrusion and the second protrusion are respectively. The silver abuts against the inclined surface, thereby constituting the filler for the cooling tower.

According to this configuration, in a state where the fillers are in contact with each other, the first protrusions are fitted into the first flow channels of the counterpart filler or the second protrusions are fitted into the second flow channels of the counterpart filler.

Therefore, the fillers which are in contact with each other are prevented from moving in both directions in which the valleys or the peaks cross each other, so that they are aligned with each other in the horizontal plane, so that the fillers are not joined to each other by applying an adhesive or the like between the fillers. The fixing of the fillers is accomplished by fixing only not to flow.

Thus, there is no need for a very time consuming and costly task of applying and aligning the adhesive to the fillers in laminating the fillers to form the laminate.

As a further feature of this invention, the longitudinal one end of the valleys and peaks of the filler may be formed in the vertical direction to form an inlet for the coolant.

Even though the flow passage of the coolant formed by the fillers is inclined, the inlet of the coolant is vertically formed, so that the coolant sprayed from the nozzle of the cooling tower is effectively introduced into the flow channel of the filler.

On the other hand, the valley portion and the peak portion in the center of the longitudinal direction of the filler may be formed in the vertical direction.

In this case, two shorter fillers can be formed by cutting the completed filler in the center, so that fillers having different lengths can be manufactured in a single facility.

Hereinafter, the concrete configuration of the filler according to the embodiment of the present invention and the structure of the laminate in which the fillers of the embodiment are laminated as described in detail, and the operation of the coolant flowing in and flowing from the laminate will be described.

In the following description and throughout this specification, the term 'length direction' refers to the direction in which an element extends when it is elongated, and the term 'vertical direction' refers to an end that exits from the end where the coolant flows in the stack. It means a straight direction of the furnace, 'thickness direction' means the thickness direction of the sheet of the filler formed by molding the synthetic resin in the form of a sheet.

In addition, the terms 'surface' and 'backside' define a surface exposed to a plane of one side of the filler as 'surface', and a portion exposed to a plane of the opposite side is defined as 'backside'.

First, the configuration of one filler will be described with reference to FIGS. 2 to 5.

The filler 100 is a thin synthetic resin sheet, which has a width and height suitable for use as a filler for a cooling tower as a whole, and is formed in a quadrangular shape on a plane.

Referring to FIG. 2 together with FIG. 3, which is an enlarged view thereof, the upper side in the drawing is an upper side through which cooling water is injected from the nozzle of the cooling tower, and the left side is left at an angle of about 30 ° with respect to the vertical direction from the upper side to the lower side. A hill 10 and a valley 20 extending inclined are alternately formed in the width direction of the filler 100.

On the other hand, in this embodiment, the peak and valleys are inclined at 30 ° with respect to the vertical direction, but the present invention is not limited to this angle, and at any angle as long as the coolant flowing into the filler is sufficient to flow downward by gravity. It may also be formed obliquely.

Figure 4 is a longitudinal cross-sectional view cut in the direction intersecting the longitudinal direction of the valleys and peaks in FIG.

Referring to FIG. 3 and FIG. 4 together, the peak portion 10 is formed to protrude in the thickness direction of the filler, and the valleys 20 are concave in the thickness direction of the filler.

The surfaces 11 of the peaks 10 have the same height and are formed flat and are disposed on a common first plane 13, and the back surface 22 of FIG. 5 also has the same height. It is formed flat and is arrange | positioned at the common 2nd plane 23.

Since the surfaces 11 of the hill 10 and the back surface 22 of the valleys 20 are parallel to each other and spaced apart from each other by the protruding height and the depth of depression, the first plane 13 and the second plane 23 are They are parallel to each other and spaced a predetermined distance apart.

Both sides of the hill 10 are formed with a flat inclined surface 30 extending to the valley 20, the hill 10 and the inclined surfaces 30 form a trapezoidal shape, the valleys 20 and the inclined surfaces on both sides Field 30 also has a trapezoidal shape.

The trapezoidal space surrounded by the surface 21 and the inclined surface 30 of the valley part and opening to one side forms a first flow channel 19 through which the coolant flows, and the back surface 12 and the inclined surface of the peak 10. The trapezoidal space surrounded by 30 and open to one side forms a second flow channel 29 through which coolant flows.

Although the names of the ridges and valleys are used throughout the description and specification of this embodiment, the ridges and valleys are only relative concepts, and referring to FIG. 6 which shows the backside of the filler 100, the backside of the filler, The valleys 20 are in the form of a protruding mountain to form a surface on which the back surface 22 of the valleys 20 protrudes, and in the form of a valley in which the peaks 10 of the filler are recessed.

As such, the names of the ridges 10 and the valleys 20 in this embodiment and throughout the specification are only relative to each other as a relative concept seen in a specific direction of the filler, and thus, the filler 100 of this embodiment is opposite to each other. The peaks projecting in the direction are alternately formed.

5 is a longitudinal cross-sectional view cut along the longitudinal direction of any one of the valleys, referring to this view, the mountain portion 10 is formed with a first protrusion 14 at regular intervals along the extending longitudinal direction have. The first protrusion 14 forms a plane protruding from the surface 11 of the peak 10 in the thickness direction of the filler 100, and the side surface (141 in FIG. 5) is disposed between the first protrusion 14 and the surface 11 of the peak 10. Formed.

In addition, the second protrusions 24 protruding from the rear surface 22 of the bone portion 20 are formed at regular intervals along the longitudinal direction of the bone portion, and the second protrusions 24 are also similar to the first protrusions 14. A plane protruding perpendicularly from the rear surface 22 of the valley 20 is formed, and the side surface 241 is formed between the rear surface 22 of the valley 20.

The first protrusion 14 formed in each of the peaks 10 is formed at the same position along the extending direction of the peak 10 from the end portion 15 of the filler and the second formed in each valley 20. The protrusion part 24 is also formed in the same position along the extension direction of the valley part 20 from the edge part 25 of a filler.

In addition, the first protrusion 14 and the second protrusion 24 which are placed side by side in the width direction of the filler are arranged at the same distance from the end of the filler. That is, in the peak 10, the first protrusion 14 and the surface 11 are alternately formed in the order in which the first protrusion 14 is formed first from the end and then the surface 11 is formed, and the valley portion 20 is formed. The second protrusion 24 and the surface 21 are alternately formed in the order that the second protrusion 24 is formed first from the end, and then the surface 21 is formed.

The side surface 141 of the first protrusion and the side surface 241 of the second protrusion are not formed perpendicular to the longitudinal direction in which the peak 10 and the valley 20 extend, respectively, and the peak 10 and the valley 20 are formed. Is inclined in a direction opposite to the direction inclined with respect to the vertical direction.

In the filler 100, both longitudinal ends 15 and 17 of the peak 10 and both longitudinal ends 25 and 27 of the valley 20 have no first and second protrusions 14 and 24 formed therein. The peak portion 10 and the valley portion 20 are formed in the vertical direction without being inclined.

In addition, the first and second protrusions 14 and 24 are not formed in the center of the longitudinal direction of the filler 100, and the connecting portions 16 and 26 are not inclined with respect to the vertical direction. Formed.

After the connecting portions 16 and 26 are formed with one filler material, the filler is cut along the connecting portions 16 and 26 and bisected in the longitudinal direction to divide one filler into two sheets when a short filler is required in the cooling tower. It is intended to be used.

Referring to FIG. 3 again, the peaks 10, the valleys 20, and the inclined surface 30 are formed with beads 18, 28, and 38 which protrude or dent from the surface thereof.

These beads 18, 28, 38 are inclined in a direction opposite to the direction in which the peak 10 and the valley 20 is inclined with respect to the vertical direction, the beads are connected to each other to form a straight line in the plan view.

In addition, the beads 18, 28, 38 are formed to be spaced apart from each other at regular intervals in the longitudinal direction of the ridge 10 and the valley 20, some of the beads are formed on the first protrusion 14 and alternately Some of the beads arranged in the second protrusion 24 are formed.

These beads improve the stiffness of the filler material, and the beads are generally placed almost perpendicular to the direction in which the coolant flows, disrupting and rubbing the coolant flow, dispersing the coolant and slowing the flow rate.

Since the filler of this embodiment is formed by stacking a plurality of fillers against each other and arranged in a cooling tower, the configuration and operation of the laminates laminated with each other by providing a plurality of fillers configured as described above will be described.

7 shows a process of preparing a plurality of fillers having the above-described configuration and stacking them with each other.

The two first fillers 100 are arranged in a state as shown in FIG. 2, and the second fillers 200 are arranged in a state as shown in FIG. 6 between them. Although these 1st and 2nd fillers 100 and 200 all have the same structure, the adjacent fillers are reversed and arrange | positioned so that the mountain parts 10 and 210 or the valley parts 20 and 220 may face each other.

FIG. 8 illustrates a state in which only two fillers are stacked together in a laminate of fillers stacked in this way, and the contours of the ridges, valleys, first protrusions, and second protrusions are shown as main components of the fillers. First filler 100 The second filler 200 placed on the upper portion by a dotted line is indicated by a solid line.

FIG. 9 illustrates a longitudinal section along line D-D in FIG. 8, and FIG. 10 illustrates a longitudinal cross section along line E-E in FIG. 8.

Referring to these drawings, the first filler 100 and the second filler 200 are disposed to be in contact with the protruding peaks 10 and 210 so that the surfaces 11 and 211 of the peak are in contact with each other.

When laminating in this manner, the first flow channel 19 of the first filler is closed by being covered by the second filler 200, and the first flow channel 219 of the second filler is opened. The covered portion is covered by the first filler 100 and sealed. Accordingly, the coolant injected from the nozzle 3 and introduced from the ends of the first flow channels 19 and 219 flows along the first flow channels 19 and 219 to the opposite end.

Referring to FIG. 8, the direction in which the peak portion 210 and the valley portion 220 of the second filler are extended may be opposite to the direction in which the peak portion 10 and the valley portion 20 of the first filler extend with respect to the vertical direction. It becomes a picture state. Thus, the first flow channels 19, 219 formed between the peaks 10, 210 and the valleys 20, 220 intersect with each other and cross the flow chart of the coolant through the first flow channels.

Meanwhile, referring again to FIG. 7, the third filler 300 disposed on the second filler 200 is disposed in the same state as the first filler 100 and placed on the second filler 200, in which case The valleys 220 of the second filler 200 and the valleys of the third filler 300 come into contact with each other, and open portions of the second flow channels of the second filler and the third filler are covered by each other.

Similarly, when the fourth filler 400 is laminated on the third filler 300, the lamination is performed in the same manner as the first filler 100 and the second filler 200 are laminated.

Again, a configuration in which the first filler 100 and the second filler 200 are stacked will be described.

11 is a view as viewed from the longitudinal end of the first filler 100 and the second filler 200 in a stacked state.

Referring to this figure, the end portion 25 and the inclined surface 30 of the valley portion of the first filler 100 and the end portion 225 and the slope of the slope surface 230 of the valley portion of the second filler are hexagonal channels. To form. This channel corresponds to the end of the first flow channel 19 of the first filler and the first flow channel 219 of the second filler, which in turn results in the first flow channel 19 and the second filler of the first filler. 1 corresponds to the common inlet of flow channel 219.

The ends of the first flow channels 19, 219 are placed under the nozzle of the cooling water (3 in FIG. 1) in the cooling tower and the cooling water injected from the nozzle flows into this end.

The coolant flowing from the ends of the first flow channels 19, 219 flows down according to the gravity, but the first flow channels 19, 219 are separated from each other at their intersections and repeat to cross again. Will flow to.

Meanwhile, referring back to FIGS. 8 to 10, a configuration in which the positions where the first filler and the second filler are in contact with each other are matched will be described.

First, with reference to FIG. 9, the top portion 10 of the second filler 200 abuts and intersects on the first flow channel 19 of the first filler 100, and the surface of the top portion of the second filler is intersected. Reference numeral 211 abuts the surface 11 of the peak of the first filler, and the first protrusion 214 of the second filler protrudes from the surface 211 of the peak and thus the first flow channel of the first filler 100. It is in the state drawn in (19).

Accordingly, both end portions that are sidewalls of the first protrusion 214 of the top portion of the second filler material come into contact with both inclined surfaces 30 forming the first flow channel 19 of the first filler material 100. Since the side wall of the first protrusion 214 is inclined to coincide with the inclination angle of the valley or the peak, the side wall of the first protrusion 214 is also inclined to coincide with the angle of the inclined plane with respect to the vertical direction.

As a result, the first protrusion 214 of the top portion of the second filler is fitted into the first flow channel 19 of the first filler 100, so that the first filler 100 and the second filler 200 are shown in FIG. They do not move in the direction of the line DD of eight.

Next, referring to FIG. 10, the peak 10 of the first filler 100 abuts and crosses under the first flow channel 219 of the second filler 200. The surface 11 of the peak portion is in contact with the surface 211 of the peak portion of the second filler material, and the first protrusion 14 of the first filler material protrudes from the surface 11 of the peak portion to form the second filler 200. 1 flows into the flow channel 219.

In addition, both end portions that are sidewalls of the first protrusion 14 of the top portion of the first filler may be in contact with both inclined surfaces 230 constituting the first flow channel 219 of the second filler 200. Since the side wall of the first protrusion 14 is inclined to coincide with the inclination angle of the valley part or the peak part, the side wall of the first protrusion 14 is also inclined to coincide with the angle of the inclined plane with respect to the vertical direction.

As a result, the first protrusion 14 of the top portion of the first filler is fitted into the first flow channel 219 of the second filler 200, so that the first filler 100 and the second filler 200 are shown in FIG. They do not move in the direction of line EE of six.

As such, in a state where the first filler 100 and the second filler 200 are in contact with each other, the first protrusions are fitted into the first flow channels of the opposite filler, and thus, the first filler 100 and the second filler 200 are disposed. The filler 200 is prevented from moving in both directions intersecting with each other, thereby achieving position registration with each other in a horizontal plane.

Similarly, when the third filler 300 is abutted on the second filler 200, the second protrusion of the valley of one of the fillers is fitted into the second flow channel of the other filler in contact with each other in the horizontal plane. Matching is done.

This position registration, on the other hand, can only be achieved by simply bringing the fillers into contact with each other, without the operator having to fit the protrusions of the filler into the flow channel.

Since the first protrusions or the second protrusions protrude at a predetermined distance from the surface or the backside of the peak or valley, and the surface of the peak or valley is also recessed into the protrusion at regular intervals, the pattern and the surface on which the protrusion is disposed are disposed. The fillers are horizontally aligned with each other by the action of the pattern mating with each other and the projections being inserted into the flow channel.

As described above, the fillers of this embodiment are aligned with each other only by overlapping with each other, so that the horizontal channels are aligned with the flow channels intersecting with each other, and movement in the horizontal plane is prevented. When it is not supported, the fillers may be bonded to each other using an adhesive or the like, or may be coupled to each other without the cumbersome work of deforming the coupling protrusions and installed in the cooling tower.

The structure of the filler according to the embodiment of the present invention and the action of stacking these fillers to form a laminate that can be installed in a cooling tower have been described. However, the present invention is not limited to these examples, and the scope of the claims is set forth. Various variations, modifications and additions of elements are possible in.
